(01.242452) invention relates tothreading devices One objectof the invention is the provisionof means:tofacilitate the winding of pa threading device, i.. e., a thread; carrierand guide, [of-the netting-needle type.

Another object of theinvention is to provide an improved method.- of providing a threading device or the character describedwith a winding of thread, cord or the like. 1

A fur-ther object of the invention. is the pro.- vision ofmeans fort-holding;'a-..normally flat threading device in longitudinally-flexed bowed condition in order. to facilitate. the winding :thereon. of a coil ofthread,.cord. or the like.

Referring now to the drawingsin detaiLthere is shown in Figs.- 3 to 6 a threading member Ill which isof the netting-needletype,said-threading. member being adapted to have wound there;

be the said pm; having a bifurcated end portion .20. which is. secured to. the. adjacent end portionof the. intermediate part. 22 of the. threading. memher in any suitable way as vby rivets.,2.4. One

end 26' ofthe threading member ispointed in order to facilitate the projection of the. thread-- ingme nber through a loop. It..will. be understood thatthe threading; member ID. is. of a'size tobe conveniently held inthehand for manipulating the threading member for. .applyingfthe cord orrthread of the coil carried the desired purpose.v

In; accordance. with the. present invention, provision-,is. made for holding the threading member. H! in position.- to. facilitate the winding oithe coil or thread thereon. The holder 28 provided-for this purpose vis illustrated in. Figs. 1, 2 andmt'o 11. Said. holder is rigid andmay be fcrmed of. woodorof any other suitable materiaLfandyhas-a longitudinally curved surface on anelongated coil of. thread or .cord'fas, indi-l catecl at l2 in Fig- 2, said coilbeing wound in the -form of elongated convolutions. extending around one of the furcations .M of the bifurcated end portion and around the pin l6 whereby the coil extendslongitudinally of the threading member in a' known way. The threading member 10 is normally .flat and is formed of a plastic or other suitable stiff but 30.- at one sidev thereof and aflat surface 37. at itsopposite side. At the curved side thereof said holderis provided with-a recess. 34 to. receive one of the end portions. or furcations. [4 of thethreading deir'ice as. shown, in dotted lines, in Fig. 8 and, in fullline pin'Fig. 11, and with a recess 36 .terminatinginan undercut closed end, 31 to receive the pointed endportionlfi of said threading. member as illustrated in Figs. 8 and 11. A-. metal band38. extends transverselyaround theholderzfiinposition to overlie the end of. recess 34. and the end portion l4-of the threadingmemberlfl whichis. positioned in said recess and.-a s--clearly; illustrated. in. Figs. ,8 and, 11. Whenthe thr eadingmember H] is positioned in the holder. 28,. said threading member is flexed or bowed longitudinally thereof, conforming generally'in longitudinalzcuivature to the curved surface 3110f holder 28, while the pin [6 and one of the endportions M are disposed in spaced relation to. thesurface of. holder 28, as illustrated in Figs. 1 and 9.. The. parts of the holder 28. at the closed ends of recesses and 36 C011. stitute meansto engage vthe'opposite ends, respeotively, of threading member [0. and to hold the latter in longitudinally-flexed bowed con diti'on',.as'illustrated. in Fig. 11. (see also Fig. 9), the spaee..between- {$816. member-engaging means-being lessthan the length of said member.v Hclder 28 has a part3!) disposed laterally of recess 3fii'which, engages a part of member l0 inwardly. of its bifurcated end portion [5. for

flexible material andis provided with an openholding one ,of. the 'furc'ations l4, namely the thereby for v furcation which is not disposed in recess 34, in spaced confronting relation to the curved surface of the holder. An integral rib 4| is positioned in recess 26, centrally, to form a bearing for the pin l8 of threading member 18 to form a firm support for said pin when the threading member is positioned in the holder. As illus-v trated in Figs. 9 and 11, when the threading member I8 i mounted in the holder 28, the pin l6 and one of the furcations II are displaced from the general line of curvature of the bowed threading member, thus providing room for the looped ends of the convolutions of the winding formed on said threading member. It will be understood that when the threading member ID is thus held in holder 28 a length of cord, thread or the like, can be easily wound on the threading member, with the convolutions extending longitudinally of said threading member as illustrated in Fig. 2, the opposite ends of said convolutions engaging the pin at the sidethereof adjacent the opening I8 and the forked end of the threading member near the end portion or furcation M which is spaced outwardly from the curved surface 30 of the holder 28 in confrontingrelation to said surface.

In accordance with the present invention, it is preferred to rotate the holder 28 with the threading member ID mounted therein for winding the cordon said threading member. For this purpose, holder 28 is mounted on a rotary shaft 48 of the winding apparatus 42 illustrated in Figs. 1 and 2. More particularly, holder 28 is provided with a shaft-receiving opening 44 and with a nut-receiving recess 48. As illustrated in Fig. 1, the holder is mounted on the threaded end 48 of shaft 40 and is secured to said shaftfor rotation thereby in any suitable way, the securing means being here shown as a nut 49 which is positioned in the nut-receiving recess 48 and by a nut 50 which engages the flat surface 32 of holder 28. Shaft 4|] is journalled for rotation in a bearing 52 carried by a frame member 54. The means for rotating shaft 40 whereby to rotate holder 28 comprises as here shown a pulley 55 mounted on said shaft and connected to a drivingpulley 58 by means of a belt 50. As here shown pulley 58 is operated by a, hand crank 62, but said pulley can be power operated if desired. It will be observed that holder 28 is mounted for rotation about an axis substantially normal to the cord of theatre of longitudinal curvature of the threading member H! in the bowed condition thereof whereby said threading member is rotatedin itsown plane for the winding of the cord or thread thereon. The cord or thread C to be wound on the thread carrier is supplied to the latter from a spool S which as illustrated in Figs. 1 and 2 is mounted for rotation in bearing arms 64 fixed to the base 68 of the frame of the apparatus. From the spool S the cord C extends through a guide opening 68 in the arm 18 of a. bracket 12 which as here shown is secured to the bearing member 52. A cord tensioning device 14 is mounted on the arm 18 of bracket 12 by means of an attaching bracket '16 which is secured to arm 10 of bracket'll. Said tensioning device comprises a disk 18 mounted on a pin 80 and a companion disk 82 which is movable longitudinally of pin 80 and which is spring pressed toward disk '10 by a spring 84, the pressure of which is adjustable by a nut 86 threaded on the outer end of pin 80. The cord C, in passing from the supply spool S to the threading member I 0 in the holder 28, is frictionally engaged by disks I8 and 82 whereby to-tension the cord between said tensioning device 14 and the threading member 18 while the latter is rotated for forming the winding thereon. If desired, a brake of any well known type may be applied to the spool S to tension the cord between said spool and the tension device 14.

It will be understood that in utilizing the apparatus of the present invention for forming a winding on the threading member ill, the latter is placed in the holder 28 as described above and that after one or two convolutions of the cord are wound on the threading member by hand, the shaft 48 is rotated thereby to rotate the holder 28- and the threading member ID carried thereby for completing the winding operation, the cord being drawn from the spool S by the tension imparted to the cord as a result of the rotation of the threading member ID in the rotating holder 28. When the desired length of cord is wound on the threading memher In, the latter is removed from the holder 28 by disengaging the end 14 from the recess 34 and the end 28 from the recess 36.

'While I have shown and described the presently preferred mode of practicing my invention and the-presently preferred apparatus embodying the same, it will be understood that various changes may be made without departing from the underlying idea of the invention within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
